nun-STAMP.

Be it known that I, CHARLES S. ELLIS, a citizen of the United" States,residing at Chicago, in the county of Cook and State of Illinois,have-invented certainnew and useful Improvements in Time-Stamps, ofwhich the following is a description, reference being had totheaccompanying drawings,

forming a part ()iitlliS specification, in which corresponding lettersof reference in the different figures indicate like parts.

The object of my invention is to provide a simple, cheap and compactform of timestamp in which the works of an ordinary watch may be soutilized as to enable the movable stan'iping-dies to be connected to thehour and minute hand arbors at the back of the case.

A further object is to utilize the dial printing die as a shieldtoprotect the movable dies from injury by enabling them to be normallywithdrawn out of the plane of the latter at all times except during theinstant of making an impression.

Moreover, it is my purpose to cushion the several parts from shock andespecially to (protect the arbors upon which the movable dies areplaced, from injurious or positive stress during the operation ofstamping.

I accomplish said objects in' the manner hereinafter more particularlydescribed and particularly pointed out in the claims.

In the drawings, Figure 1 is a side eleva- .tion of a device embodyingthe features of my invention, Fig. 21s a bottom view there of, Fig. 3 isa view in'which the outer case and the annular die are shown in sectiontaken upon the line 3, Fig. 2, viewed in the direction of the arrowthere shown, Fig. 4: is a bottom. view showing the back of the watch.case and movable dies, the annular die portion with its yielding framebeing removed, Fig. 5 is a bottom view of said annular die portion, andFig. 6 is a vertical seetional view of the'outer frame taken upon line6, Fig. 4, the inner or watch case proper,

being shown partly-in central section.

Referring to the drawings, a represents generally a frame portion formedfrom sheet metal and preferably rectangular in shape having a peripheraldepending flange 0 and a flat upper face portion 0, in which is formedacircular bezel (Z, Figs. '1, 3 and 6, for the reception of the usualwatch crystal e. The watch case f. Figs. 3, 4 and 6, is in-Sjieeiiicatibn at Letters Patent. amni noa flied Inn's Laos. Serial No.438,6Q8.

closed within the outer ztiame a, a notch 9, Figs. 1, 2 and t beingformed in the latter to receive the usual winding-stem h which projectstherefrom. Four studs 2', Figs. 3, 4: and 6 are rigidly attached to theinner face of the plate 0 and depend therefrom. Thesestuds'project'looselythrough perforations in laterally extended bracketswhich are at.- tached rigidly. to the periphery of the watch, caseShoulders .lc, Fig. 6, are rigidly attached to the studs 2' near theirlower ends, and between said shoulders and the brackets j are interposedcoiled springs Z, .while like springs m are interposed between "saidbrackets and the plate This construction not only serves to hold thewatch-case faway from the plate 0 but yieldingly suspended beneath thecrystal 6 so that the hands may be seen the same asin any watch.

The minute hand arbor n, Fig. (3, is ex,- tended outwardly through theback of the case and has rigidly attached thereto a disk 0, likewiseshown in Figs. 2 and 4, to the face oi which is secured a minute hand orstamping die ,0 formed from rubber or.

train at the front of the watch and which are interposed between thehour and minute hand arhors. its a result of the action of said train,the die x is caused to complete its cycle once in twelve hours, whilethe diep corresponds in its IllOYQll'lGllll to the minutehand of thewatch.

Loosely inserted within the casing a, from beneath, is a rectangularsheet metal I casing, generally designated by t, which is provided witha flat bottom portion to having a central opening therein and upwardlyextended flanges or side walls a). The latter are provided with verticalslots 211 Fig. 3, through which are loosely projected retain-- ingscrews n which are tap ed into the flanges Z), and also pass throng 1 arigid bail a forming a support for a handle a iio - desired. 15 the day,month and year, may be inserted 45 which might, otherwise occur.

Coiled springs w are placed upon the lower ends of the studs 2' and bearagain t the plate u as Well as against the shoulders Zr, thus serving topush the plate u downwardly in the position shown in Figs. 1,

321ml 6, the extent of downward movement being limited by the slots 1).

An annular die ch, Figs. 1, 2, 8, 5 and 6, is formed upon the lower faceof the plate 14,

which die is formed from a suitable yield ing material, such, forexample as india rubber, and is intended to indicate the hours, ,minutesand such other matter as may be Removable rubber type showing in asuitable'slot 1 The operation of said device is as follows; The stamp isplaced in the position shown in Fig. 1 with the annular die 11:,n'eviously inked, resting upon the surface to be stamped. Upon applyinga downward pressure to the handle, the annular die, Wltl'l the case 01,is caused to yield against the action of the springs I.I) until itsmovement with reference to the case a is arrested by the shoulders Zr,which are so placed as to cause said arrest when the tace ot the die toand that of the dies 7') and s are in substantially the same plane: itbeing understood that said movement. should be sullioient to permit aproper impression to be made by said dies 7) and s. The latter, beinlocated directly upon the minute-hand arbor, it is of the utmostimportance that provision should be made to protect. said arbor fromshock or undue stress, not only during the time of n'iaking animpression, but. at all other times. Should the dies 7) and a tend toprotrude too far when the 40 movement of the plate u is arrested by the'plane common to that oi the other dies,

,7 against the springs m, therel'iy yiehftingly maintaining the watchcase in a normal po sition. The tact that the annular die :0 is normallyheld. in a plane below that of the hour and minute marking dies, notonly serves to protect the latter from ii'ijurious contact when thedevice is not in use, but, by its out 'ard moven'ient, tends to preventthe ink from accumulating in the space be tween the annular die and theothers and clogging the latter, thereby tending to stop the watch.

By placing the i'noving dies directly upon the minute hand arbor, i amenabled to greatly simplify the construction amt-reduce the cor-5t ol'the device while providing a very small compact. and etlective stamp.

liaving thus described my invention, I claim:

1. ln a. time-stam the crm'ibination oi a watch movement, hour andmimitemarking dies mounted upon the minute hand ar her at the back otthe watch, gears tor connecting said hour n'iarliing die with saidminute hand arbor to cause an hourly rotation of said die, a dialstamping die. having hour and minute divisions, and means tor cushioningsaid lion and minute marking dies upon making an impression.

In a time-stan'ip, the combination ot a watch-movenient, hou r andminute marl in; dies mounted upon the n'iinute-haml arbor at the back ofthe watch, a dial stampinsi die having hour and minute divisions, saiddie being free to be moved in and out (ii a.

and. means for cushioning said last. named dies upon n'iakh'ig anii'npression.

In testimony whereof, l have signed this specification in the presenceof two subsrribing witnesses, this 29th day of lviay 1908.
